PATENT oFFlcE FRANK HABTIAN, F KENSINGTON, -LONDON, ENGLAND rnm'rmeArrLuNcn Application led September 3, 1927, Serial lo. 217,482, and inGreat Britain September 18, 1926.

This invention relates to printing and like appliances applicable to webdelivery apparatus. Whilst the apparatus is more especially applicableto web delivery apparatus ,5 in'general the invention is moreparticularly applicable to apparatus for delivering gummed strips. Theobject. of the present invention is to provide a simple and compactappliance by means of which advertisements, notices and so forth may beapplied to a roll tated so that an impression will be produced on thepaper or the like. The roll of paper or the like is preferably sosupported that whilst it is being unrolled it bears with sub--stantially uniform pressure upon the printing roller or rollers. Thepressure may either be produced by gravity, by springs or equivalentmeans, and the arrangement may be such that either the roll is pressedagainst the printing roller or rollers, or the printing roller orrollers are pressed against the roll of paper or the like. When theprinting appliance is combined with a frame for supporting gummed paperthe appliance is provided with a device for moistening the gummedsurface of the paper after an impression has been made on the paper.Beyond the moistening means there is provided a cutter or like device soas to facilitate the tearing olf of the moistened strip. When the stripis torn olf there is usually a tendency for the paper or the like toroll up thus drawing the paper backwardly. This is liable to causeblurring or smudging of the impression and in order Y to avoid thisdifficulty there is provided a device for engaging the paper at a pointsubstantially opposite the end of the moistening device. This engagingdevice preferably.l

consist of one or more sharp pointed projections or pins which areadapted to pierce the paper and engage therewith. The engaging devlcethus also serves to hold the paper or the like away from the moisteningdevice whilst the apparatus is not in operation. One or more ink ductsfor supplying the inking rollers and also the moistening device may beeither permanently mounted in the frame of the appliance or may be madeseparate therefrom and adjustable therein.

The printing surface on the printing roller may be in the form of arubber 'pad wound round the roller or may be in the form ofinterchangeable type or plates.

The invention will now be described by way of example, in connectionwith apparatus for printing upon a roll of gummed paper as shown in theaccompanying drawings where- H12- Fig. 1 showsa side elevation of theappa- -ratus Fig. 2 shows a plan view, the supporting arms, roll ofpaper, the device for engaging the paper, and the cutter or the likebeing omitted, and

Fig. 3 shows a detail.

In the construction 'illustrated a printing roller 1, is mounted inbearings 2, on a base 3, and an inking roller 4, bears against thesurface thereof. A single inking roller 4 is preferably used when thetype or the like on the printing roller 1 is only to be inked with onecolour, but if separate rows of type are to be inked with differentcolours then a separate inking roller is provided for each colour, or asingle inking roller suitably subdivided, is

Y used. The inking roller 4 is mounted in bearings 7 provided on thecontainer 5.

The inking roller 4 is supplied with ink from an ink duct preferablyconsistincI of a container', which is completely closed with theexception of a hole for the passage of a wick 6. This container 5 isadapted to be adjustably fitted into the 'frame 3 of the machine, so asto enable the inking roller 4 to'be brought into correct relation withthe printing roller 1. The adjustment is effected by means of set screws8, passing through spring plates 9 and springs 8', but may also beeffected by means of set screws passing through elongated slots in angesprovided on'the container 5 and screwing into the frame of the appliance.

The wick 6 which conveys the ink from the container 5 to the inkingroller 4 may pass either directly into the container 5 or may be fittedinto -a tube or sleeve adapted .to be iittcd into the container 5.

When diii'erent coloured inks are to be used separate ink containers 5are provided for each different-ly coloured ink or the container 5 isdivided into separate compartments each of which is provided with itsseparate wick and if desired with a tube or sleeve For the purpose ofmoistening the gummed paper a water container 10, of substantially thesame construction as the ink container 5,

is provided. This container 10 is also adjustably mounted in the frame,preferably in the same manner as the ink container 5.

The wick 11 of the water container 10 serves to apply moisture to thegummed sur-` face of the paper.

Substantially opposite the moistening wick 11 there is provided on theframe 3 a sharp pointed projection, pin or the like 12 which is adaptedto engage ywith the paper A as this vis severed by being drawn across acutter 13,

perforator or other suitable device for facilitating the tearing oli' ofthe gummed strip. By its engagement with the paper or the like thisprojection or pin 12 also serves to hold the paper away from themoistening wick 11 when the apparatus is not in use and as a shortdistance separates the projection 12 from the cutter or the like 13there will always be a suiiicient amount of paper beyond the pin 12, asindicated at 14, which can be gripped by the lingers in order to draw afurther length of paper through the apparatus..

In the frame 3 are pivotally mounted two arms 15 which are adapted tosupport between them a shaft 16 on which the roll of paper A or the likeis mounted. This roll is adapted to bear on the printing roller orrollers 1 so as to be printed upon as it is drawn out of the machine. Inorder that various widths of paper may be accommodated the arms 15 areprovided with bosses adapted to,

` which is pivotally mounted in the frame.

This shaft 18 is preferably provided at its ends with projecting pins 19adapted to engage with recesses in a pair of screw members 2O engagingwith the frame 3 and form ing the bearings for the shaft 18. It willhowever be understood that the pins 19 may be formed on the screws 20and the recesses in the shaft 18. The shaft 16 is provided with annulargrooves 21 formed by collars 21L arranged at different positionsaccording to the width of paper which is to be printed upon. Adjacentthe printing roller 1 there are mounted in the frame 3, a pair of guidearms x22 which extend over the printing roller 1 and are capable ofadjustment on a shaft 24, by means of set screws 23 so as to be set in aposition according to the width of the paper or the like in order toguide this over the printing roller 1. The shaft 24 is preferablyprovided at its ends with milled heads 25, so as to enable it to beturned in order to lift the arms 22 for placing the roll of .paper inposition. In order to facilitate threading the roll of paper or the likeon the shaft 16 one of the arms 15 is preferably provided with a slot 26so that it can be conveniently disengaged in order to permit of the rollof paper A or the like being readily threaded on the shaft 16. This slotis preferably provided on the underside of the arm. ln order to mount aroll of paper A on the shaft 16, the arm 15 provided with the slot 26,is swung upwardly on the shaft 18 and the roll of paper isplaced on theshaft 16 with one side against the arm 15 in which the shaft 16 ismounted. The slotted arm is now lowered and the slot 26 therein isbrought into engagement with one of the grooves 21 according to thewidth of the paper roll and thus serves to hold the` paper roll A inproper position on the shaft 16.

Between the printing mechanism and the moistening device is arranged aguide roller 2( and this is so arranged thatthe roll of paper bearing onthe printing mechanism has the free end passing around the guide j andconsequently the weight thereof is reduced the pressure by which thepaper bears upon the printing roller will be substantially uniformthroughout.
